' Specification of Letters Patent.

Patented Feb. 18, 1906.

Application filed lay 10.1907. Serial No. 372.901.

To all wiwin it may concern: Be it known that I, SWINFEN BRAMLEY-'MOORE, a subject of the King of Great Britters, of which the followingis a full and complete specification.

This invention relates to an'im'proved construction of liquid meter. 1

In the accompanying drawings which illustrate this invention:-Figures 1,2 & 3 are views in sectional elevation showing one from of theapparatus; Fig. 1 showing the parts in the positions they oceufpy whenthe iquid has just commenced to ow into the measuring vessel; Fig. 2showing the parts in the positions they occu y when the measuring vesselis nearly fu l, the inlet valve having shut off the supply; and Fig. 3showing the parts. in the positions they occupy when the measuringvessel has descended and the bulk of the fluid passed out of themeasuringvessel into the case. Fig. 4 is a view in side elevation,partly in section, showings. modification, the respective parts being inthe same positions as they are shown in Fig. 1.

Throughout the views similar parts aremarked with like letters ofreference.

Referring to Figs. 1, 2 & 3. In a suitable case a is a rising andfalling vessel b-hereinafter called the measuring vessel. This vessel iscarried by two arms It (only one of which is seen in the drawing)pivoted at h to the case a. On or in the top of the case a is a chamber0 provided with an inlet passage a leading into said chamber, theopening into said chamber being .closed by a spring-controlled valve d.The chamber 0 is provided with a siphon outlet pipe on leading into thecase a above the vessel b. Mounted in suitable guides in both thechamber 0 and the vessel b is a vertically arranged rod e adapted tooperate the valve d through the rockmg lever e pivoted on the exteriorof the chamber c, and at a suitable position on this rod is a shoulderor collar. On the bottom of the vessel 1) are ivoted two rocking leverse e the inner en' s of. which contact the shoulder or collar on therod eand the outer ends are ada ted to engage the bottom of the vessel b. inthe measuring vessel b is a float e which, when the said vessel isempty, rests on the outer ends of the levers e e and so operates to keepthe valve (1 open. In the bottom of the measuring vessel is an openingleading into the lower part of the case a, the said opening being closedby a valve f adapted to e opened by the descent of the mensuring vesselwhich causes the stem f of the valve to contact the bottom of the casea. The lower part of the case a is provided with an outlet siphon pi el. Pivoted at g to the case a are a air 0 counterweights g and g eachcarried y an arm 9 Thesecountetweights are connected to the measuringvessel by the arm g and the link 7c connected to the arms h.

The weight of thecounterweight g is equal to a predetermined portion,say fiveeighths, of the weight of the liquid admitted to the measuringvessel at each operation of the apparatus. and. the weight of thecounterweight g is slightly in excess of the weight of the measuringvessel and its appurtenances. In the case a is a float which isconnected by a link j with an arm 1 pivoted to the case 41, preferablyat the same point It as the levers It. The free end of the arm 7' isshaped to engage a stud g on the counterweight 9 so as to lock it in itsraised position until the vessel 1) has discharged the bulk of itscontents. In

' order to prevent a vacuum being, formed in the chamber a it isprovided with a small air hole such as a The action of the apparatus isas follows 1* Assuming the apparatus to be empty and that liquid ispermitted to flow into the pi e a, itpasses through the valve (1 into te chamber 0 and from thence through the siphon pipe a into the measuringvessel 1) which is at its highest position. As the liquid accumulates inthe vessel b it causes the float e to rise, which thereby releases therod e and allows the valve (1 to be closed by its spring, therebyshutting off the supply of liquid when the predetermined quantity haspassed into the chamber 6. When a prede 'termined quantity of fluid inthe chamber a has passed into the vessel 1) its weight overbalances thecounterweights g and g and the vessel begins to sink, and when itreaches its lowest. position the counterweights have been raised to sucha position that the center of gravity of the counterweight g isapproximately in a vertical plane with the pivot on which it swings sothat its influence is negative. As the Vessel b sinks and reaches itslowest position the stem f of the valve fcontacts the bottom of the casea and thus opens After this locking the said valve and allows the liquidto flow out of the measuri vessel b into the lower part of the case a.the -li uid rises in said case the float j operates to 100 thecounterweights and so prevent them raising the said vessel and restoringit to its h' best position.

is efiecte the outlet siphon pipe comes mto action and empties the caseWhlOh causes the float 1' to sink and unlock the counterwe' hts, therebyallowing the vessel to be raise As the liquid asses out of the vessel 6the float c sinks an coining in contact with the rockers e o crates themso as to lift the rod e so that w en the vessel rises the said rod econtacts the lever e and thus opens the valve d. In due course themeasuring vessel is again filled 1 with liquid, when the sequence ofoperations is automatically repeated until either the suppl of liquid iscut off or the flow of liquid out o the case ais stopped automaticall bythe level of the liquid in a receiver reaching such a level as to stopthe action of the siphon outlet'pipe Z. V V

In the modification shown by Fig. 4 the float e operates the valve (1through an arm n which is pivoted E) the case a and connected to thefloat e by a link n. The arm n is connected with one or both of thelevers h by a lever n pivoted at n to one or both of the levers h, theone end of said lever n engaging the free end of the arm n and the otherend engaging a finger n sliding in the to of the case a and adapted tocontact the va ve d so as to o erate to open it. To prevent anyossibility of the measuring vessel partially descending from its highestposition and then forming a erfect balance with the counterweight an soremaining in a midway posi- 'valve f is opened by a projectionf on itshead engaging a stop a on the side of the case a as the measurin vesseldescends. is connected t rough the link j? with an arm m pivoted on thepivotal shaft g carrying the arms of the counterweights, and to w ichthe arm 9 is fixed, so that it o erates directly to control the time atwhich t e measuring vessel will rise.

The apparatus is provided with any suitable recorder', but this forms nopart of the present invention.
